Triple star system in the constellation Vela

p Velorum (abbreviated to p Vel) is a triple star system in the constellation Vela. Parallax measurements by the Hipparcos spacecraft put it at a distance of 87.5 light-years, or 26.8 parsecs from Earth.[1] It is visible to the naked eye with a combined apparent magnitude of 3.83.[2]

The primary component is a spectroscopic binary whose components have an orbital period of 10.21 days. The inner spectroscopic binary consists of two F-type stars, a subgiant and a main-sequence star.[2] There is a companion star which is a white A-type main-sequence star, with an apparent magnitude of 5.76.[3] It is separated 0.361 arcseconds from the primary and has an orbital period of 16.651 years.[3]
